BRAKE.

To all whom it may concern. 1 e

Be it known that l, Josnrrr H. DICKIN- soN', a citizen of the UnitedStates, residing at Cranford, in the county of Union and State-of NewJersey, have invented certain new and useful Improvements in Brakes, ofwhich the following is a specification;

My invention relates to an improved brake more particularly adapted foruse in phonegraphs and the like. lts features and advantages will beapparent to those skilled in the art from an understanding of thefollowing description in connection with the drawings. In the latter,Figure 1 is a fragmentary top plan view of a talking machine embodyingthe present brake; Fig. 2 isan enlarged vertical section partly inelevation on the line 2 2 in Fig. 1 looking in the di? rection of thearrows; Fig. 3 is an underneath plan of the brake detached; Fig l is atop plan of the same; and Fig. 5 is a side elevation looking at Fig. 1from the left.

Describing now the devices of the drawings, 1 is an elbow' lever pivotedto a base plate 2 by screwl3. The plate is secured by screws 4: as acover over a recess (not shown) formed in the board 5, the recess beingprovided to receive the projecting underneatlrparts of the device. 6 isa brakeshoefor contacting with the periphery of the turn-table and isappropriately mounted on the upstanding end 7 of one arm of theelbow-lever 1 (compare Fig. 5). The other arm ofthis lever is notched atS and has a knob 9 by which to operate it. Intermediate the handle 9Vandthe pivot 3, said lever arm has a downwardly projecting pin 10 workingin a slot 11 in the plate. The pin is headed on the underside of theplate and i 12 is bent in such a way as to form a notch or recess in itat 12 which produces a looking effect on the pin 10 (Fig. 3) so that thelatter is maintained stationarily at one end of the slot 11 with thebrakeshoe 6 in Oh,

or unbraking position. Further, this spring Specification of LettersPatent. Patented Jan. 15, 121%. Application filed January 29 1915.Serial No. 5,045. i

leased by operating its handle or notched end into the dotted positionwhereuponthe notch 12 in the spring-arm looks it by means of the pin 10in oif? position. Vice.

versa to apply the brake it is merely necessary to press the handle endof the lever in the direction'of the full lines sufiicientlv to forcethe pin 10 out of locking engagement with the springarm 12, whereuponthe brake-lever is tripped and said spring-arm completes the motion ofthe elbow lever by camniing it into its braking position shownbythe fulllines in Fig. 4e. c

The brake can also be operated from the outside of the cabinet byswinging a small crankarm or finger piece 15 on the end of a rock-shaft17 whose bearings are at 18 and lilrespectively and whichlias an innercrank arm 20 projecting up through a slot in'the shelf 21 and in theescutcl eon plate 22 intothc notch 8 in the end of the elbow lever.' inshort the brake can be applied or released from the outside of the caseby swinging the finger piece 16 in one direction or the other, as wellas from the inside by operating it through the knob 9;

An anti-friction hearing may be provided between the springarm 12 andthe pin 10, comprisinga loose sleeve 10 on the pin 10 to be in rollingcontact with said springarm.

The shoe 6 consists of a piece of material 6 such as leather (Fig. 4)secured by a rivet 6 to the upstanding end 7 of the elbow-lever andfurther comprises a piece of leather 6 glued as a facing to the piece 6.

)Vhat I claim is 1. In a brake mechanism, the combination of a brakemember movable between an 011' position and an on position, and providedwith a rigid projection; and spring means cooperative with the brakemember, having a notch directly engageable with said projection to locksaid member in one position, and also having a cam portion adapted towipe against said projection when thelatter is released from said notch,so, as to force t the off movement oi sa1d lever in position said memberinto its otherposition.

2. In a brake mechanism, the combination of a brake member movablebetween an ofif i position and an on position, and provided stitutingthe solemeans for throwing said member from one of such positions to theportion adjacent said notch adapted to wipe with a rigid projection; anda spring, conagainstsaid projection, when the latter is released fromthe notch, so as to force said member into its other position. i

3. In a brake mechanism, the combination of a two-armed brake levermovable between an off position and an on position and having a brakingpart on one arm, and a lateral projection on the other arm; a platewhereon said lever is pivoted, having a slot in which said projection isarranged to travel; and spring means cooperative with thebrake member,having a notch directly engageable with said projection to lock saidCopies of this patent may he obtained for member in one position, andalso having a cam portion adapted to wlpe agamst said pro ection, whenthe latter 15 released from said notch, so as to force said member intoits other position; oneend of said slot limit mg the on movement of saidlever, and I the other end limiting its oil? movement in position forthe automatic engagement of said projection by said notch. o

4. In a brake mechanism, the combination of a two-armed brake levermovable between anfotf position and an on position and having abrakingpart on one arm, and a lateral projection on the other arm; a platewhereon sa1d lever is pivoted: and spring .means cooperative with thebrake member,

having a notch directly engageablewith said projection to lock saldmember in one position, and also having a cam portion adapted to Wipeagainst-sa d pro ection,

when the latter is released from said notch,

sition; means being provided for arresting for the automatic engagementof said projection by said notch. i

5. In a brake mechanism, the combination of an angular brake levermovable between an off position and an on position, and having a"brakingipart on one arm, and a lateral projection. on the otherarm aplate whereon said lever isjpivotedja fixed pro jection on said plate;and a strip ot springwire having its middle portion coiled about saidfixed projection and its extremities. or legs crossed under tension; oneof: said legs being held fixed, and the other bent to form a notch fordirect engagementwith the first named projection to lock the lever inone position, and also to form a cam portion adjacent said notch adaptedto wipe against said first-named projection, when the latter is releasedfrom the notch, so as to force said lever into its other position." V I'6. In a brake mechanism, thecombinatio'n 01" a brake member movablebetweenantotf position andfan on positionand provided with a rigidprojection; spring means c0- operative with the brake member, having anotch directly engageable Withsaid pro ection to lock saidmember intolifposition, and also having a cam portion adaptedto "ipe against saidprojection, when the latter is released from said notch, so as to forcesaid member into its on position; and means connected to positivelyimpart an initial movementto said brake member with re. lation tosaid'spring means, to effect the release of said projection from saidnotch."

In' testimony whereof, I have "signed my name to this specificationinthepresenceof two subscribing Witnesses, this 27th day of January, 1915.
